Ladle-fastening.



` lower surface of the trunnion rin fillers positioning the ladle in the trunnion ringand, as they fill'the slots 6 in the trunnion ring, serving also to prevent the ladle being dislodged or being removed from the trunnion ring in the ladle dumping operations, l.

In placing the ladle 2 in the trunnion ring 3 the ladle is suspended above the trunnion ring 3 and is turned until the lugs 5 thereof register with the vertical slots 6 in the inner surface of the annular trunnion ring. lThe ladle is then lowered into position inthe ring 3 until the upper surfaces of the lugs 5 on the ladleare in a plane below the bottom surface of the trunnion ring 3, the lugs ,Ipassin downwardlyl through the slots 6. he la le is then rotated or turned on a vertical axis so as to move the lugs 5 into a position between the slots 6 in the trunnion. When in this position the lugs 5 will engage the lower surface of the trunnion ring and prevent the removal 'or dislodgment of the ladle, when the ladle 2 is tilted in the dumping opera-v tions.y When lugs are employed on the bottom of the ladle the lugs are positioned on the ladle so as to project between the adjacent edges of the intersecting straps and by engagement therewith prevent rotation of the ladle in the trunnion ring 2. The notched plates 13 are then fastened to the 3 the lugs being positioned in the notch 1n these plates and in this way the ladles 2 are securely fastened in' place on the trunnion rings.

` 'lhe advantages of my invention will be apparent to those s killed'in the art.

The 'apparatus is simple and is easily and cheaply constructed.

By the use of my improved fastening means the ladles are securely held 1n position on the trunnionrings and the ladies may be tilted without liability of accident i or damage to the apparatus by reason of the ladle becoming displaced.

Modifications in the construction and arrangement of the apparatus may be made without departingv from my invention as defined in the appended claims.
